Abstract
The present disclosure relates to a delay control circuit arranged for adding delay to a signal. The delay control circuit includes a driver circuit arranged to receive a first signal and to output a second signal. The driver circuit includes a variable load arranged for outputting the second signal by adding delay to the first signal. The delay control circuit also includes a control circuit arranged to receive the first signal and to control the variable load of the driver circuit based on a current state of the first signal and on a control signal indicative of an amount of delay to be added to the first signal in the current state.
Claims20
A delay control circuit arranged for adding delay to a signal, comprising:
- a driver circuit arranged to receive a first signal and to output a second signal, wherein the driver circuit comprises a variable load arranged for outputting the second signal by adding delay to the first signal;
- and
- a control circuit arranged to receive the first signal and to control the variable load of the driver circuit based on a current state of the first signal and on a control signal indicative of an amount of delay to be added to the first signal in the current state.
A direct digital radio frequency modulator comprising a plurality of converter circuits, wherein at least one of the converter circuits comprises a delay control circuit, wherein the delay control circuit comprises:
- a driver circuit arranged to receive a first signal and to output a second signal, wherein the driver circuit comprises a variable load arranged for outputting the second signal by adding delay to the first signal;
- and
- a control circuit arranged to receive the first signal and to control the variable load of the driver circuit based on a current state of the first signal and on a control signal indicative of an amount of delay to be added to the first signal in the current state.
A method, comprising:
- receiving, by a driver circuit, a first signal;
- adding, by a variable load of the driver circuit, a delay to the first signal;
- outputting, by the driver circuit, a second signal, wherein the second signal comprises the first signal with the added delay;
- receiving, by a control circuit, the first signal;
- and
- controlling, by the control circuit, the variable load based on a current state of the first signal and on a control signal indicative of an amount of delay to be added to the first signal in the current state.
